To all whom it may concern ,Be it known that I, GIUSEPPI P. VUONO, a citizen 'of the United States, dent of thevborou'gh of Brookl cgunty of ork, vented certain new and useful Improvements in Silk-Finishing Machines, of which the following is a specification.

This invention the exact to the fabric necessary desired finish.

Another object of the invention is to provide an improved construction of paste de livering and applying means-adjustable to thereby. 5

The finishing 'paste ,'n the is heated to maintain the same in a state by means of a steam drum 42 to which steam is supplied through a pipe 43'. The roll of silk to be finished is" supported on a core or splndle 44 ournaled in :suitable bearings 45 on the frame and the. fabric is passed over guide. rollers 46, 47 and 37, thence under. pressure roller .33 and over roller 38, thenceunder guide'roller 48 and over guide roller 49, thence about a suitable tension device 50, and-the edge thereof secured to a core or spindle 51.

The p'o'nter is slidably guided in a slot'57 in bloc 21 and is adapted to be locked in its adjusted position by a thumb nut 58.

By shifting roller 17 until it just touches roller 16 and then adjusting the pointer to zero on the scale and locking the pointer in it will beobvious that its adjusted position, the pointer will indicate the extent to which the roller 17 is subsequently forced into the soft roller 16.

.a: scale 72- on the frame of'the machine. I The roller 59 has a covering of hard rubber; and the roller 60 has a covering of soft'rubber.

The operation is as follows:

44 carrying the -roll.of silk is mounted in the bearings 45 and the fabric is passed over rolls 46, 47

and 23 and between the large roller 16 and pressure roller-33, thepressure roller being held out of contact with roller 16' by-cam 40 as shown in- Fig. 4. Cam 40' is then swung to the position shown in Fig. 3 and the machine started, whereupon rolls 16 and 23 will feed the fabric in the direction indicated by the arrows on-the drawing and the operator .passes the advancing abric about the remaining guide rolls and tension device, as shown, and connects the end thereof to the spool or core' 51. The cam 40 is then swung to Figs. 1 and 2 in whichposition the downward pull of the fabric as it passes over -roller 38 during the continued-operation of the machineservesto cause the hard pres- SIHGJOllGI 33 to press" into the soft roller 16. The hard controlling roller 17 is ad justed toward the soft roller '16 'until it presses into the soft roller to the desired extent, according to the character of finish to be given the fabric.

cause roller 17 to press into roller 16 an even distribution of the roller 16 is obtained, notwithstanding the the position shown in adjusting the rollers 16 and 17 td I finishing paste upon the I inevitable slight variationsof. parts of the perimeters of the rolls from. true cylindrical form, or inexact roller can be regulatedwith the necessary nicety. The soft roller will always yield alinement of the shafts sufficiently to prevent the hard roller from squeezing all of the paste picked up by the The employv ment of a hard controlling roller affords an accurate regulation of the quantity of paste,

soft roller back into the tank.

as the squeezing-action of the rollers can be more accurately controlled than'if two soft rollers were employed and a greater pres- 1 sure or more powerful squ'eezing action can be obtained within the necessarily narrow limits of adjustment of the controller roller.

The surface of the soft rubber covering of the applying roller has minute cells or cavities therein which receive the glue, so that the A e up more glue at the same time By providing a soft, porous, non-absorbent, inherently rewithin of the 1t is in engagement with theroller,

silient applying roller, the

amount of glue delivered to the silk may be nicely varied narrow limits by the squeezing action hard controlling roller.

By providing a hard pressure roller pressing the fabric against a soft applying roller, the fabric is pressed into the yielding 'surface of the applying roller and all of the paste on the applying roller is forced into the fabric. It will also be obvious that this construction insures an even application of the paste to the silk notwithstanding inequalities in the surfaces of the pressure and applying rollers, or inexact alinement of said rollers.

By adding a soft controller roller, as shown in Figs. 10 and 11, the capacity of the machine for applying different varieties of finish to the fabric is increased. When it is desired to apply relatively large quantities of paste the hard roller 59 is shifted out of contact with soft roller is pressed against the applying roller causing deformation of both rollers a c the squeezing point. Owing to the fact that the surfaces of both rollers are yieldable a relatively large quantity of paste may pass between the rollers.

In order that the regulating roller 17 inay be readily cleaned when desired, a cleaning brush 73 is provided adapted to be shifted into and outof engagement with the roller. The brush 73 comprises a bar, preferably somewhat shorter than the roller 17, and having a strip of sponge or other suitable material secured to one side thereof. The brush is held at its ends to a pair of arms 7 51 by means of screws 75 which pass through elongated slots 76 in the arms. he arms 74 are pivotally held at 77 to the roller. supporting means and are adapted to be swung upwardly against stops 78 formed on. the arms 22 to support the brush in its inopera tive position. The brush is provided with a handle 79 for shifting .the same into and out of engagement with the roller 17 and for reciprocating the brush longitudinally;1 when t e pin and slot connections between the brush and arms 74 lpermitting endwise reciprocation of rus What I claimis: J
